REGULATOR-SUPPORT FOR INCUBATORS- Specification of Letters Patent.

Patented May 21, 1907.

Application filed December 22, 1906- Serial No. 349,119.

To all ZU/MHH/ it may concern:

Be it known that I, MANANDER Mor'r JOHNSON, a citizen of the United States, residing at Clay Center, in the county of Clay and State of Nebraska, have invented certain new and useful Improvements in Regulator- Supports for Incubators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in supporting devicesfor incubator regulators.

The object of the invention is to provide a supporting device of this character by means of which the thermostat that regulates the heat supplied to the incubator will be supported in proper position above the e gs, so that the same temperature that a ects the eggs will also affect the thermostat and cause the same to operate the regulating mechanism to produce the desired temperature within the incubator.

A further object is to provide means on said supporting device for holding a thermometer in position to be readily observed throu h the door of the incubator.

Wit the above and other objects in view the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings :--Figure 1 is a vertical sectional view through an in.-

cubator, showing the application of the in- Y vention thereto; and 2 is a perspective view ofthe re lator supporting bracket removed fronr t e incubator.

Referring more particularly to the drawings, 1 denotes the incubator, which may be of any desired form and construction and in which is arranged the usual egg supporting tray 2. On the inner wall of one end of the incubator is adapted to be secured the improved regulator supporting bracket 3, which consists of a horizontally-disposed arm 4. At one end of the arm 4 is formed an attaching plate 5, by means of which the bracket may be screwed or otherwise secured to the end wall of the incubator, as shown.

The arm 4 has formed therein adjacent to its outer end an upwardly-projecting curve or bend 6. On the upper side of said bend 6 is formed a pair of upwardly-projecting apertured bearing lugs or ears 7, between which is pivotally mounted the regulating lever 8.

One end of the lever 8 projects through a suitable opening in the end of the incubator, and is connected to the lower end of the damper rod 9. The outer end of the lever 8 is provided with an aperture, through which the lowerfend of the rod 9 passes, said end of the rod being threaded to receive athumbnut 10, by means of which the connection.

On the arm 4 adjacent to the inner side of the bend '6 therein is mounted a pair of thermostat disks 15, which may be of the usual or any desired constructionadapted, to be expanded and contracted by the temperature of the incubator.- The inner end of the lever 8 is connected to the upper side of the thermostat disks, so that said lever will be operated by the expansion and contraction of the disks and will in turn operate the damper mechanism connected with the heating apparatus and thereby regulate the temperature within the incubator.

The inner end of the arm 4 projects beyond the thermostat and is provided with a vertically-dis osed aperture'or recess 16, with which is a apted to be enga ed the lower end of a right angularly-formed t ermometer supporting rod 17. On the right an larl proilecting portion of the rod 17 is a apte to be ung a thermometer 18, said thermometer being thus supported in a position to be offected by the same term erature of the egg and the thermostat. he osition of the thermometer will be such t at it .may be readily observed through the glass door of the incubator, so that the temperature of the eg s may be seen at a glance.

y providin a supporting bracket for the regulating mec anism of the incubator and constructing the same as herein shown and described the length of the regulating lever 8 is increased between its pivotal connection and its connection with the damper mechan-' IIO affected by the same temperature in which the eggs are afl ected, as hereinbefore described.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advantages of this invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters-Patent, is

1. A regulator sup ort for incubators comprising a horizontal y disposed sup )orting arm having a bearing on its upper side, at a point between its ends, adapted to support the regulating lever, said arm further havin a vertical plate at its outer end to attach Stlit bracket to the incubator, and means at the inner end of said arm to support a thermometer at the level of the thermostat disks.

2. AI'egulator support for incubators comprising a bracket consisting of a horizontallydispose'd arm adapted to project inwardly over ithe egg tray in the incubator and to support the regulator thermostat above said egg tray, apertured bearing lugs formed on said arms adapted to pivotally support the regulator lever, and a supporting rodadapted to be engaged with the inner end of said arm and to support a thermometer on a level with said thermostat disks, substantially as described.

3. A regulator support for incubators coniprising a bracket consisting of an attaching plate adapted to be secured to the inner wall of one end of the incubator, an integrally formed inwardly-proiecting supporting arm formed on said plate adapted to support the regulator thermostat in proper position over the egg tray of the inculmtor and having an opening in its inner end, an upwardly-extending bend formed in saidv arm. apertured bearing lugs on the upper end of said bend adapted to pivotally-support the regulator lever, a ri ht angularl \'-l' rmed rod engaged and seated in said opening in the inner end of said arm adjacent to said thcrmost at disks and to support a-thermometer in a horizontal position on a level with said thermostat disks, substantiallv as described.

In testimony whereof l have hereunto set my hand in presence of two subscribing witnesses.
